Balance-of-Plant

The term "balance-of-plant" contains all components of a fuel cell system except the stack itself. This includes pumps, sensors, heat exchanger, gaskets, compressors, recirculation blowers, intercoolers or humidifier.

In order to ensure the appropriate work within the fuel cell system, these components need to be qualified under "fuel cell conditions". For those applications HORIBA FuelCon has the Evaluator BOP series that covers various solutions for anode and cathode side.
